Title: Velocity responsive actuating means
IPC: G01P1/10
Filed: 1965-06-25
Abstract: A switch suitable, for example, for controlling a vehicle automatic gear change, of the kind comprising an " S "-shaped flexible blade S coupled at X to a speed-responsive member (P, Figs. 1 and 2, not shown) driven by eddycurrent drag from a rotating magnet (A), and wherein the blade S is thus snapped between two fixed contacts B and B1 at two different vehicle speeds, is characterized in that the vehicle speed at which the snap action occurs in one direction is adjustable by adjustment of the position of one fixed contact. The adjustable contact is carried on, or moved by (Fig. 4, not shown), a spring-urged lever L which also acts as an armature of an electromagnet E the current through which is controlled, for example, by a rheostat or switch operated by the accelerator pedal. In the embodiment of Fig. 5 (not shown), a single speed-responsive member P is coupled to two such " S "" blade arrangements to provide two respective gear changes. If the accelerator pedal is depressed beyond its normal travel the adjustable contact may move the blade S over dead centre to effect a quicker change of gear. Instead of an electromagnet to control lever L a pneumatic, hydraulic, or simple mechanical linkage may be used.

Patent ES-337702-A1 (ES)
Title: Gun with a floating breech bolt
IPC: F41A3/40
Filed: 1967-03-07
Abstract: A firearm comprises a breech mechanism slidable within a breech frame 7. The breech mechanism consists of a bolt head 1 mounted slidably within a breech bolt 9, spring 10 being interposed therebetween and tending to urge the head 1 away from the bolt 9. The bolt head 1 is locked in its firing position by a nib 3 which engages with one end in recess 15 in the bolt head, the other end of the nib being formed with a foot 5 preferably having four flat faces 16, 17, 18, 19. In the locked firing position the face 16 engages an abutment 6 of the breech frame 7. On firing the firearm, for example, through the hammer 23 striking the firing pin 14, the firearm recoils and, in response to the recoil, the breech bolt 9 is urged forwardly against the spring 10 to delay the unlocking of the bolt head 1, (Fig. 2, not shown). The breech bolt 9 is then urged rearwardly by the compressed spring 10 and by the residual gas from the fired cartridge, a face 22 of the breech bolt 9 engaging the face 18 of the nib foot 5 to slide the face 17 over the abutment 6 and withdraw the forward end of the nib 3 away from the bolt head recess 15, thus unlocking the bolt head 1, (Fig. 3, not shown). The bolt head 1 then recoils away from the breech to eject the spent cartridge.
Patent ES-339981-A1 (ES)
Title: Improvements in or relating to Overload Protection Apparatus for the Propulsive Engines of Ships having Variable Pitch Blade Screws.
IPC: F01L1/00
Filed: 1967-04-29
Abstract: Overloading of an engine driving a ships variable (reversible) pitch propeller is prevented by a cam A connected to a controller or the engine fuel pump actuating a contactor 1 which de-energizes a solenoid operated valve E1, thereby stopping flow to and from the hydraulic ram V of the pitch changing mechanism, thus arresting change of pitch, further movement of the cam A resulting in further overload actuating a second contactor 2 which causes energization of the valve E1 resulting in supply to the hydraulic ram V in a direction to bring about a change of pitch in the reverse direction, i.e. if blade pitch is being increased actuation of contactor 1 arrests the increase and subsequent actuation of contactor 2 will then reduce the pitch. Hydraulic supply is through a valve E2 which is closed on operation of the contactor 1 so that the supply is through a restricted by-pass RD, the ram V thus operating slowly in the overload range. Reversers I1-I4, normally open when the ram V is in the zero pitch position, are closed one way or the other by a cam B whose movement corresponds to the movement of the ram V when the latter is in a position corresponding to ahead or astern pitch.

Title: Cable insulation test apparatus including a fluid containing cylindrical test bushing having a plurality of electrodes and condenser stacks positioned along a pair of insulating tubes connecting the electrodes
IPC: G01R31/02
Filed: 1967-06-26
Abstract: Apparatus for continuously measuring the ionization inception or extinction voltage of the insulation of a cable 11 as the latter is moved through the apparatus comprises a high voltage electrode 26 connected to two earthed electrodes 27, 28 by insulating tubes 29, 30 so as to form a cylindrical channel through which the cable moves, and two banks of capacitors 31, 32 each having one terminal connected to the h.v. electrode and the other terminal to ionization voltage measuring equipment, the arrangement being such that when ionization occurs in a void in the insulation, pulses V B , V A (say 7 appear at the outputs of the capacitor banks 31 and 32 respectively, and the highest values of VB/VA and VA/VB respectively give the ionization inceptions and extinction voltages (assuming right to left motion of the cable, viewing Fig. 1). The apparatus further comprises a grounded metal guard 35 surrounding the whole assembly and the outputs of blue capacitor banks are fed through high pass filters 43, 49 (to remove mains frequency interference) and amplifiers 44, 50 to a dividing circuit 45 which forms the ratio VA/VB or VB/VA. The enclosures 15, 16 contain a high dielectric constant liquid 13, there being a wiping member 21 to remove air bubbles from the surface of the cable insulation. The output pulses of the dividing circuit 45 are fed to a continuous recording device 51, to a voltmeter 53, or to an alarm system 52 which gives a warning when the ionization voltage falls outside acceptable limits.
Patent ES-344565-A1 (ES)
Title: Thin film associative memory
IPC: G11C15/02
Filed: 1967-08-29
Abstract: In an associative memory, columns of magnetic memory elements store respective tags and receive equal amounts of electromagnetic energy, the elements being perturbed in accordance with an input tag, and the amount of energy remaining in each column after absorption by the elements of that column being measured directly to identify the most-closely matching column. In Figs. la, 1b microwave energy from an oscillator 5 is supplied to branch lines 8, 34 threading anisotropic (hard axis) thin-film magnetic elements 3 constituting the columns of the two matrices shown. A bit is stored at each intersection of a column 3 with a perturb row line 15, 25 by write-in means not shown. Each column in Fig. 1a stores a tag and each row in Fig. 1b stores a corresponding data item. Such bits of an input tag in an input register 12 as are not masked out by a select circuit 16 control bi-polar pulse generators 14 to drive the perturb lines 15, so that at each bit storage position in the Fig. la matrix, the microwave energy from oscillator 5 is attenuated less and more in the cases of agreement and disagreement (between input and stored bits) respectively. The output energy level from a given column produces an output from a respective threshold amplifier 22 in the case of a complete match with the input tag, to read out the corresponding data item from the matrix of Fig. 1b as shown through amplifiers (diode detectors) 36. The threshold of the amplifiers 22 is adjusted by sources 28 in accordance with the number of bits masked out by select circuit 16, and if a complete match is not found may be successively lowered to get the closest match. In a first modification, an extra perturb line in the Fig. 1a matrix is controlled by a variable pulse generator as a substitute for having the threshold on the amplifiers 22 variable. In a second modification the bits of the input tag are gated to the pulse generators 14 in turn by a ring counter. In this case, a single bit mismatch in a given column produces an output from the corresponding threshold amplifier 22 to set a respective latch. The latch (if any) still not set at the end of the tag comparison selects the data item to be read out.
